From 535fb5a2d4347801439fbb51fa07cd0317183cee Mon Sep 17 00:00:00 2001 From: Xi Ruoyao <xry111@xry111.site> Date: Fri, 25 Oct 2024 02:08:03 +0000 Subject: [PATCH 035/188] LoongArch: genopts: Add infrastructure to generate code for new features in ISA evolution LoongArch v1.10 introduced the concept of ISA evolution. During ISA evolution, many independent features can be added and enumerated via CPUCFG. Add a data file into genopts storing the CPUCFG word, bit, the name of the command line option controlling if this feature should be used for compilation, and the text description. Make genstr.sh process these info and add the command line options into loongarch.opt and loongarch-str.h, and generate a new file loongarch-cpucfg-map.h for mapping CPUCFG output to the corresponding option. When handling -march=native, use the information in loongarch-cpucfg-map.h to generate the corresponding option mask. Enable the features implied by -march setting unless the user has explicitly disabled the feature. The added options (-mdiv32 and -mld-seq-sa) are not really handled yet. They'll be used in the following patches. gcc/ChangeLog: * config/loongarch/genopts/isa-evolution.in: New data file. * config/loongarch/genopts/genstr.sh: Translate info in isa-evolution.in when generating loongarch-str.h, loongarch.opt, and loongarch-cpucfg-map.h. * config/loongarch/genopts/loongarch.opt.in (isa_evolution): New variable. * config/loongarch/t-loongarch: (loongarch-cpucfg-map.h): New rule. (loongarch-str.h): Depend on isa-evolution.in. (loongarch.opt): Depend on isa-evolution.in. (loongarch-cpu.o): Depend on loongarch-cpucfg-map.h. * config/loongarch/loongarch-str.h: Regenerate. * config/loongarch/loongarch-def.h (loongarch_isa): Add field for evolution features. Add helper function to enable features in this field. Probe native CPU capability and save the corresponding options into preset. * config/loongarch/loongarch-cpu.cc (fill_native_cpu_config): Probe native CPU capability and save the corresponding options into preset. (cache_cpucfg): Simplify with C++11-style for loop. (cpucfg_useful_idx, N_CPUCFG_WORDS): Move to ... * config/loongarch/loongarch.cc (loongarch_option_override_internal): Enable the ISA evolution feature options implied by -march and not explicitly disabled. (loongarch_asm_code_end): New function, print ISA information as comments in the assembly if -fverbose-asm. It makes easier to debug things like -march=native. (TARGET_ASM_CODE_END): Define. * config/loongarch/loongarch.opt: Regenerate. * config/loongarch/loongarch-cpucfg-map.h: Generate. (cpucfg_useful_idx, N_CPUCFG_WORDS) ... here. --- gcc/config/loongarch/genopts/genstr.sh | 92 ++++++++++++++++++- gcc/config/loongarch/genopts/isa-evolution.in | 2 + gcc/config/loongarch/genopts/loongarch.opt.in | 7 ++ gcc/config/loongarch/loongarch-cpu.cc | 46 +++++----- gcc/config/loongarch/loongarch-cpucfg-map.h | 48 ++++++++++ gcc/config/loongarch/loongarch-def.h | 7 ++ gcc/config/loongarch/loongarch-str.h | 6 +- gcc/config/loongarch/loongarch.cc | 31 +++++++ gcc/config/loongarch/loongarch.opt | 20 +++- gcc/config/loongarch/t-loongarch | 21 ++++- 10 files changed, 244 insertions(+), 36 deletions(-) create mode 100644 gcc/config/loongarch/genopts/isa-evolution.in create mode 100644 gcc/config/loongarch/loongarch-cpucfg-map.h diff --git a/gcc/config/loongarch/genopts/genstr.sh b/gcc/config/loongarch/genopts/genstr.sh index 972ef125f..bcc616e98 100755 --- a/gcc/config/loongarch/genopts/genstr.sh +++ b/gcc/config/loongarch/genopts/genstr.sh @@ -25,8 +25,8 @@ cd "$(dirname "$0")" # Generate a header containing definitions from the string table. gen_defines() { cat <<EOF -/* Generated automatically by "genstr" from "loongarch-strings". - Please do not edit this file directly. +/* Generated automatically by "genstr" from "loongarch-strings" and + "isa-evolution.in".
